Web Development Services — React & TypeScript Engineering
Engineering robust web software that scales effortlessly. From complex cloud dashboards and business portals to high-traffic consumer web applications, we write clean, maintainable, type-safe code that performs under load.
Engineering Standards & Principles
Type-Safe Architecture
Strict end-to-end TypeScript eliminates entire classes of runtime bugs, accelerates refactoring, and guarantees predictable data contracts.
React Server Components
Next.js 15 App Router keeps heavy JavaScript on the server, shipping lean HTML to the client for lightning-fast First Contentful Paint.
Robust Data Layer
Optimized relational schemas (PostgreSQL, SQLite, MySQL) with connection pooling, transactional integrity, and automated migrations.
API & Microservice Integration
Clean REST and webhook integrations with Stripe, WhatsApp API, Telegram, SendGrid, OpenAI, and internal enterprise ERPs.

Frequently Asked Questions About Web Development
Which frontend frameworks and tech stacks do you specialize in?
We specialize in Next.js 15 (App Router with React Server Components), React 19, strict TypeScript, and Tailwind CSS v4. For backends, we build using Node.js, Next.js API Routes, C# .NET Core, and PostgreSQL/MySQL databases.
Do you build both frontend interfaces and backend databases?
Yes. TechUsar provides end-to-end full-stack engineering. We design database schemas, configure ORMs (Prisma, Drizzle, Entity Framework), write secure authentication logic, and integrate third-party APIs.
How do you guarantee website performance and fast loading?
We optimize Core Web Vitals from day one: zero Cumulative Layout Shift (CLS), sub-second Largest Contentful Paint (LCP), asset optimization with next/image, route prefetching, and edge caching.
Can you migrate an existing legacy website to Next.js and TypeScript?
Yes. We frequently migrate legacy WordPress, PHP, or outdated React codebases to modern Next.js 15 App Router architectures, improving page speed and developer maintainability.
